Complete Coil Set - SF-8617

SF8617_MAIN.jpg

Overview

These high-quality coils and laminated iron cores provide an effective introduction to electromagnetic theory. Purchase them individually or as a complete set. The coils are color-coded and each coil is labeled with the number of turns and the direction of the winding. Use them to investigate:

  • Electromagnetism: Show how the magnetic field can be increased by increasing the current, by adding an iron core or by using a coil with more turns.
  • Induction: Pass a magnet through a coil and detect the resulting electromotive force (EMF) with a galvanometer. Show how the EMF depends on the number of turns in the coil and on the relative velocity of the magnet and coil.
  • Transformers: Mount coils onto the U or E-shaped iron cores to demonstrate mutual inductance and transformer theory. Then connect a load to investigate power transfer. Investigate basic transformer theory with an AC power supply and a voltmeter. Advanced principles require a high power output function generator (Model PI-8127 or PI-9598) and an oscilloscope. For better experiments and demonstrations, use a computer with PASCO's ScienceWorkshop Interfaces.
